Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Horsetail (Equisetum arvense) has been traditionally used in folk medicine for various urinary tract issues, including bedwetting (nocturnal enuresis). The traditional rationale stems from horsetail's reputed astringent and mild diuretic properties, which were believed to help tone and strengthen the bladder, thereby reducing involuntary urination at night. Historical herbal texts from Europe and Asia document its use in remedies for urinary incontinence and bedwetting, particularly before the advent of modern pharmaceuticals.

However, scientific validation for horsetail's effectiveness in treating bedwetting is extremely limited. Few studies specifically address its use for nocturnal enuresis, and those that exist are often small, poorly controlled, or anecdotal. No robust clinical trials have demonstrated a clear benefit of horsetail over placebo for this condition. Most modern references to horsetail for bedwetting continue to cite historical usage rather than new research findings.

Given this, while horsetail's use for bedwetting is justified by tradition, the quality and quantity of supporting evidence is low, meriting a rating of 1. Anyone considering horsetail should be aware of potential side effects and drug interactions, and consult a healthcare professional, especially when dealing with children.
